Extrasolar Planets

In the Aarhus exoplanet group we search for and study the properties of extra solar planet systems. We strive to gain a better understanding how these systems form and evolve. Ultimately we hope to understand if some of these alien worlds might represent suitable habitats for life outside the solar system.

For this we use space based as well as ground based observatories including the Kepler, K2 and TESS NASA missions. In the southern hemisphere we make use of ESOs Very Large Telescope and La Silla observatories and in the northern hemisphere we are regular visitors at the Telescopio Nazionale Galileo and the Nordic Optical Telescope. We also conduct observations at the fully robotic Aarhus led SONG telescope. Our research is focused on studying the architecture of extra solar planet systems and on developing novel methods to study their atmospheres.

Some examples:

  • Orbital eccentricities in single and multi transiting planet systems
  • Spin-Orbit angles (obliquities) in single and multiple planet systems
  • Obliquities in short  and long period double star systems,  including Tatooine like systems
